 DW0992.The horizontal coordinates were established by classical geodetic methods
 DW0992.and adjusted by the National Geodetic Survey in June 1996.
 DW0992.The horizontal coordinates are valid at the epoch date displayed above.
 DW0992.The epoch date for horizontal control is a decimal equivalence
 DW0992.of Year/Month/Day.
 DW0992
 DW0992.The NAVD 88 height was computed by applying the VERTCON shift value to
 DW0992.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DW0992
 DW0992.The Laplace correction was computed from DEFLEC99 derived deflections.
 DW0992
 DW0992.The geoid height was determined by GEOID99.

 DW0992
 DW0992'DESCRIBED BY US ENGINEERS 1948 (DHK)
 DW0992'THE STATION IS LOCATED ABOUT 13 MILES AIR LINE SOUTHWEST OF
 DW0992'BLYTHE, ABOUT 5 MILES AIR LINE EAST AND A LITTLE NORTH OF
 DW0992'WILEY WELL, ON THE NORTHERNMOST AND HIGHEST POINT OF THE
 DW0992'MULE MOUNTAINS.  THE STATION MARK IS A CORPS OF ENGINEERS
 DW0992'U.S. ARMY BRONZE DISK, SET IN A DEPRESSION IN BEDROCK, WITH
 DW0992'THE ROCKS AROUND IT PROJECTING ABOUT 8 INCHES, STAMPED, TRI

 DW0992'SET FLUSH, STAMPED, MULE MTN 1948.
 DW0992'
 DW0992'TO REACH FROM THE POST OFFICE IN BLYTHE, GO WEST ON U.S.
 DW0992'HIGHWAY 60 FOR 14.7 MILES.  AT THIS POINT THE STATION MOUNTAIN
 DW0992'IS DUE SOUTH 182 DEGREES TRUE.  TURN LEFT, SOUTH, AND PICK
 DW0992'WAY ACROSS SAND DUNES TO THE BASE OF MOUNTAIN IN A LARGE
 DW0992'DRAW TO A WASH.  CROSS WASH, THENCE TURN RIGHT, SOUTH, AND
 DW0992'FOLLOW RIDGE ALONG THE EAST SIDE OF WASH TO THE AZIMUTH MARK
 DW0992'AS DESCRIBED ABOVE.  FROM HERE CONTINUE SOUTH TO A HIGHER
 DW0992'RIDGE.  FOLLOW THIS RIDGE FOR APPROXIMATELY 0.5 MILE TO THE
 DW0992'END OF TRUCK TRAVEL ON A RIDGE IN THE CENTER OF A WIDE DRAW.
 DW0992'FROM THE END OF TRUCK TRAVEL, PACK SOUTH UP CANYON, THENCE
 DW0992'EAST TO THE HIGHEST POINT AND STATION.  A 1-HOUR PACK.  A
 DW0992'FOUR WHEEL DRIVE VEHICLE IS REQUIRED TO CROSS SAND DUNES.
